Any ideas?

Try buying a new module if it works it is the module if not return the module.

Is the new alternator charging. Could be as simple as running low on voltage. Should be charging 13.8-14.2 runnning around 1200-1500 RPM.

I like this... except the part about trying to return the module. Most parts houses around here don't allow you to return electrical stuff (condensers, modules, voltage regulators, etc.) I do keep a module in the trunk for exactly the reason TT302Z28 said (usually when the module goes it doesn't work at all). I have been stranded once before this way.

Gotta agree with SpeedBump. Around here you can only return electrical parts if they are still in the plastic and unopened.

X2 on the alternator. Seems like the likely culprit to me.

Thanks for the input guys.I ran some tests this past week and the ignition module tested fine according to my meter and testing info from pertronix,also tested the coil and that seems to be fine(about 2.5ohms).Now I'm not sure where to go,maybe plug wires or possibly a fuel issue?

Why did you change the alternator? My guess is the replacement alternator has a bad diode and is putting a lot of noise or voltage spikes into the electrical system, which is probably not making the Pertronix Ignitor too happy.
